SPECIFICATION forming part of Letters Patent N o. 574,722, dated January 5, 1897'.V

Application filed April l 3, 1896;

To all whom it may concern:

Beit known that we.'GU1LLERMo A. FAEINI, residing at London, England, and FRANCIS X. GAUDRIE, residing at Port Hope, Durham county, Province of Ontario, Canada, subjects two ends or sides of an object or article at the Y same time, and it is particularly designed for burnishing the en ds of sheetmetalcans,which at the present time it is found desirable to burnish to prevent the too-rapid rusting of the same.

The invention consists in detail in two adjacent separated burnishing devices with a feed, and, further, in the construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

.In the drawings, Figure l is .a side elevation of our improved machine. Fig. 2 is a top plan. Fig. 3 is an end elevation looking from the right of Fig. l. Fig. 4 is a vert-ical central longitudinal section. Fig. 5 is a crosssection on line y y, Fig. 2; and Fig. 6 is a diagram elevation illustrating the construction of a cut-off designed for feeding a single can at a time.

We have shown on this frame two horizontal parallel burnishing-brushes O, driven by suitable power connections, with guide-rails or a table D between and a feed mechanism for feeding the cans over that guideway, comprising the endless belt E, travelingover rollers F F', arranged above the guideway or table, these parts being constructed so that the rotation of the brush will burnish the ends of the can as the can is fed along by the roller over the interposed guideways or table, the can being rolled by the movement of the belt, so that all portions of its ends will be presented to the brushes during its movement.

While we deem this the preferable form and arrangement of parts, we do not desire, to be limited to the same, as we believe the spirit of our invention includes any machine having burnishing mechanism in juxtaposi- Serial No. 587,334. (No model.)

ing through the side of the frame, as plainly Y shown in Figs. 2 and 5.

The guide-rails D we likewise preferably adjust by means of similar-adjusting-bolts l. In order to provide for cans of different size we preferably journal the shaft of the roller Fin a vertically-slotted standard J, as shown in Fig. l, holding it in the lower position of said slot by the tension of springs J Near the opposite end of the device we arrange the inclined discharge chute or runway K, by means of which the cans are, delivered from the machine. Both of the brushes are driven in any suitable manner. We have shown them belted from a pulley L in the lower part of the frame, which is driven from the driveshaft L. The two brushes are shown as revolving toward each other, which with this form of brush we deem the most desirable arrangement. The teeth or bristles of the brush we have shown as spirally arranged, and this is preferable, as it assists somewhat vin reducing the power required to feed the can through the machine.

Any suitable feed device may be employed for feeding the cans the desired interval apart into the machine. We have shown the construction illustrated fully in Fig. 6. This embodies a lever a, projecting with its upper end into the path of the supply-runway?) below the initial portion of the belt. This lever bears against a second lever c, pivoted below the runway and held normally in the position shown in full lines in Fig. (i by the tension of the spring d. This lever c ateach end has the pins e e', which are adapted to be alternately projected into the path of the cans through the runway, the operation of the device being as follows: The cans being IOC piled up on the runway behind the pins c, the feed-belt traveling over the guideway and actoperator places a can in position to be fed by ing as a feed for the cans. the feed-belt, which can, as it is fed forward, 3.
